  1. 1. Advances in Thermal Insulation : Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

    Författare :Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

    Sammanfattning : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. LÄS MER

  2. 2. Sperm Whales : Social Organization and Global Genetic Structure

    Författare :Thomas Lyrholm; Mark Stoneking; Stockholms universitet; []

    Sammanfattning : The social organization of most mammals is characterised by female philopatry and male dispersal. This thesis examines the social organization of sperm whales, Physeter macrocephalus, using a combination of field observations and molecular genetic techniques. LÄS MER

  3. 3. Environmental Contaminants, Recombination and Cancer : Investigations on the molecular mechanisms of spontaneous and induced recombination in the hprt gene of Chinese hamster cells

    Författare :Thomas Helleday; Mark Meuth; Stockholms universitet; []
    Nyckelord :toxikologisk genetik; Genetic Toxicology;

    Sammanfattning : Recombination results in rearrangement of the genetic material contained in the chromosomes inherited from the mother and father and this process is also involved in repairing damage to the genome. Occasionally, the machinery that performs recombination malfunctions and this may lead to illegitimate recombination events which inactivate tumor suppressor genes or activate protooncogenes.

  4. 4. Statistical Methods for Computational Markets : Proportional Share Market Prediction and Admission Control

    Författare :Thomas Sandholm; Magnus Boman; Mark Baker; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Grid Computing; Performance Analysis; Workload Modeling; Middleware; Quality of Service; Prediction; Admission Control; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : We design, implement and evaluate statistical methods for managing uncertainty when consuming and provisioning resources in a federated computational market. To enable efficient allocation of resources in this environment, providers need to know consumers' risk preferences, and the expected future demand. LÄS MER

  5. 5. Reduced Preoperative Fasting in Children

    Författare :Hanna Andersson; Peter Frykholm; Mark Thomas; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fasting; Children; Preoperative; Pulmonary Aspiration; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Preoperative fasting is recommended in order to reduce the risk of perioperative pulmonary aspiration. However, preoperative fasting may have negative effects on patient wellbeing and homeostasis. LÄS MER
